Glossary
Complete index of SUNNY M Lab roast and cup phenomena, boundary conditions, and observational terminology. Each term is versioned, dated, and subject to revision when new evidence emerges.
Phenomena Atlas — Observable Roast & Cup Phenomena
| Code | Term | Definition | Relationships | Status |
|---|---|---|---|---|
| AC | Alive Cup 活態杯 | A cup condition in which flavor states continue to shift meaningfully across the full temperature range, from the first hot sip to the final cool phase. From the first sip to the last, the flavors in the cup keep changing. | Active Documentation | |
| CDM | Cup-Driven Maturity 杯中熟成判斷 | A roast condition in which maturity is confirmed through cup observation rather than reference to roast events such as first crack, DTR, or color endpoints. It is not decided by roasting. It is decided by the cup. | Active Documentation | |
| CDV | Caramelization Divergence 焦糖化分歧 | A roasting phenomenon in which differences in energy distribution across caramelization-related reactions create distinct sensory emphases between the hot and cool stages of the cup. The hot cup speaks through one kind of sweetness. The cool cup preserves another. | Active Documentation | |
| HCM | Hot Cup Memory 熱杯記憶點 | A cup condition in which the most memorable flavor impression forms primarily during the hot phase, with the cup becoming quieter as it cools. It speaks while hot. | Active Documentation | |
| NCR | No Crack Roast 無爆烘焙 | A roast system in which the maturity confirmation mechanism does not rely on first crack as an acoustic event or bean color as a visual endpoint. The coffee has completed its cup structure. What confirms it is not the sound of the crack. | Active Documentation | |
| OP | Observation Progression 觀測演進 | The documented change in cup sensory state at different points after roast, used as a primary indicator of a batch's observable arc. The same coffee presents differently at different points in time. | Active Documentation | |
| PCM | Pre-Crack Maturity 爆點前熟成 | A roast condition in which cup maturity is established before first crack occurs, making the acoustic event no longer the starting point of development. The coffee has already been dropped. The crack comes afterward. | Active Documentation | |
| REA | Roast Event Asynchrony 烘焙事件異步 | A condition in which the timing of conventional roast events does not align with the point at which the coffee actually achieves maturity in the cup. Events and maturity do not necessarily happen at the same time. | Active Documentation | |
| TDR | Terminal Decline Roast 末段柔化烘焙 | A roast profile condition in which heat application during the terminal phase follows a deliberate, sustained, controllable decline trajectory, producing observable structural softening in the cup. Heat exits. The cup opens. | Active Documentation |
Phenomenon Boundary Archive — Boundary Conditions & Misreadings
| Code | Term | Definition | Boundary For | Status |
|---|---|---|---|---|
| CICC | Cliff-Induced Cold Collapse 陡降冷崩 | A cup-structure collapse caused by a sharp temperature drop during roasting, in which the cup may appear structurally intact while hot but breaks apart as it cools. It holds while hot. As it cools, the structure breaks. | Active Documentation | |
| EGBS | Energy Gap BT Stall 能量空白停滯 | A roasting thermal phenomenon in which bean temperature enters a near-stalled state after a rapid rise or rapid decline, creating a short window of insufficient energy progression or discontinuity in energy transfer. The curve is still present, but energy briefly stops speaking. | Active Documentation | |
| FAC | False Alive Cup 偽活態杯 | A cup condition in which apparent temperature-stage variation is present but does not constitute structurally distinct flavor states. The cup appears to shift; the shifts are intensity-dependent rather than structural. It looks like it's changing. It isn't. | Active Documentation | |
| SF | Structural Flattening 結構平坦化 | A roast outcome in which cup structure fails to differentiate across temperature stages or time, presenting a single undifferentiated flavor state regardless of observation conditions. The cup is present. Nothing is happening. | Active Documentation |
